| 摘 要： | 在地下结构抗浮设计中,较少考虑侧壁摩阻力的作用,对于侧摩阻力的的计算方法也不够明确。抗浮安全系数目前尚无统一规定,主要参照类似工程实践经验确定。在宁波轨道交通工程福庆路站抗拔桩静载试验的基础上,以地铁车站结构为研究对象,经过试验分析,对地下车站结构设计中侧壁摩阻力大小进行计算,进而考虑抗浮安全性对车站结构的临界宽度进行计算,可为地铁车站设计提供指导。

| Abstract: | In the design of underground structure, the action of the side friction is rarely considered and the determination method of the side friction is also not given in the design specification. Therefore, there is no unified regulations on anti-floating safety coefficient which can be ascertained according to the similar engineering practice. In this paper, the structure of the stations in Ningbo urban rail transit project is investigated by using the available experience and the uplift test results. The side friction of the structure is calculated; then the critical width of the station structure is ascertained when the anti-floating safety is considered. The results can provide a little of instruction on the design of metro station. |
